Genesis Model 1 VA7 Triple Bypass with Composite Restore
I am installing the 3BP v2+ board on a Genesis Model 1 VA7. I'd like to keep both RGB and Composite signal, but I couldn't get it working.
When I soldered a wire between the CXA1145 pin 20 and the bottom pad of S75 without bridging the S75 according to this Github issue: CV pad missing · Issue #14 · zaxour/TripleBypassV2Plus , I got no signal from both composite and RGB.
When I removed the wire to CXA1145 and bridged S75 pads, I got good RGB signal but the composite output is extremely dark. Does anyone has a clue about how to do this properly? Many thanks!
Here are some photos of my installation, sorry I only have those white Kynar wires but I've tested all the pads and they are connected correctly.
